# This example illustrates how to set up OAuth2 authentication credentials.
require 'adwords_api'
def setup_oauth2()
# AdwordsApi::Api will read a config file from ENV['HOME']/adwords_api.yml
# when called without parameters.
adwords = AdwordsApi::Api.new
# To enable logging of SOAP requests, set the log_level value to 'DEBUG' in
# the configuration file or provide your own logger:
# adwords.logger = Logger.new('adwords_xml.log')
# You can call authorize explicitly to obtain the access token. Otherwise, it
# will be invoked automatically on the first API call.
# There are two ways to provide verification code, first one is via the block:
token = adwords.authorize() do |auth_url|
puts "Hit Auth error, please navigate to URL:\n\t%s" % auth_url
print 'log in and type the verification code: '
verification_code = gets.chomp
verification_code
end
if token
print "\nWould you like to update your adwords_api.yml to save " +
"OAuth2 credentials? (y/N): "
response = gets.chomp
if ('y'.casecmp(response) == 0) or ('yes'.casecmp(response) == 0)
adwords.save_oauth2_token(token)
puts 'OAuth2 token is now saved to ~/adwords_api.yml and will be ' +
'automatically used by the library.'
end
end
# Alternatively, you can provide one within the parameters:
# token = adwords.authorize({:oauth2_verification_code => verification_code})
# Note, 'token' is a Hash. Its value is not used in this example. If you need
# to be able to access the API in offline mode, with no user present, you
# should persist it to be used in subsequent invocations like this:
# adwords.authorize({:oauth2_token => token})
# No exception thrown - we are good to make a request.
